Southern Christianity, a native expression of Christian groups in South America, Africa, Asia, and Oceania, has shown remarkable growth over the last century, especially in the past fifty years. Characterized by evangelical, Pentecostal, and fundamental traits, it exhibits structural disunity and strong moral conservatism. Its numerous independent groups often reject affiliation with Western denominations, reacting against the formalism and liberalism that have affected many American and European churches. Southern Christians embrace an otherworldly perspective, value the mysterious and mystical, and frequently emphasize Biblical prophecy. Their syncretistic nature allows them to blend elements from various denominations and even other religions, often crossing denominational boundaries. The defining feature of Southern Christianity is its moral conservatism, advocating traditional family values and proactive child-rearing. Culturally, it stands as a counterforce to the West, opposing economic materialism, humanistic secularism, and agnostic or atheistic liberalism. Southern Christianity rejects postmodernism and the values the West promotes, positioning itself against the current of modernism and earning a countercultural label from Western liberal elites. This clash of values intensifies as Southern Christianity has migrated north into America, particularly following the Immigration Reform Act of 1965, which facilitated immigration from regions where Southern Christianity thrives, challenging the intended cultural diversification and weakening of traditional religious influence in America.

The migration of Southern Christians into America, primarily from Latin America, Oceania, Asia, and Africa, has significantly altered the landscape of American Christianity. These immigrants, adhering to various forms of Southern Christianity, have swelled the memberships of Catholic parishes and Pentecostal churches with their devout, fundamentally conservative beliefs. This shift has transformed American Christianity from a predominantly liberal, formal denominational structure into a vibrant, fervent movement often led by small, unaffiliated sects, spurred by the unforeseen consequences of the Immigration Reform Act of 1965. Contrary to plans aimed at secularizing American culture, this wave of Christian immigrants has reinforced the presence of Christianity within the mainstream. Southern Christianity is poised to deepen the divide between America and Europe, contributing to a growing cultural and religious rift that could fracture the long-standing Atlantic Alliance. This divergence, fueled by differing interests post-Cold War, may lead to significant conflict, as the mutual commitment to liberal internationalism and multilateralism wanes. Additionally, Southern Christians, in a potential turn toward bigotry, might attempt to purge the land of what they deem false religions, forcibly ejecting various groups, including some under God's protection, in a misguided effort to cleanse the nation. The tension between Southern Christians and agnostic secularists is set to become the defining fault line in American politics, manifesting in legislation, jurisprudence, and occasionally erupting into outright persecution. This struggle will bewilder many Americans, leaving them unable to comprehend the disarray in their civil society and the failure of domestic policy. As Southern Christians push conservatism and traditionalism with self-righteousness and missionary zeal, Europeans will increasingly view America as aggressive and a threat to their way of life. Domestically, social fragmentation may lead to large numbers fleeing America to escape religious persecution, with Southern Christianity playing a significant role in the decline and fall of the nation.
